Question

I couldn’t find how to list all drawable inside another app from my app.

I managed to get drawables if I know the name, but couldn’t find how to do it with a simple loop from 1 to N.

Any of you could offer a code template to do this?

The following code already works:

mAndromedaAddonContext = createPackageContext( "com.demo.andromeda",
                Context.CONTEXT_IGNORE_SECURITY );
mPlanetsResID[0] = mAndromedaAddonResources.getIdentifier( "planet20111007081421628", "drawable", "com.demo.andromeda" );

But I want to iterate without using the resource name.
Something along those lines:
for(int i=0; i

I do have the same sharedUserId and process in the manifest file, so I have the privilege to access the resources from the other app.

Thanks in advance.

First use mAndromedaAddonResources.getAssets() to get an instance of AssetManger for the app you are targeting.

see here:
https://developer.android.com/reference/android/content/res/Resources.html#getAssets()

Then you can use the

public final String[] list (String path)

method in AssetManager class to get a list of all assets at a given path( In your case, it would be the path of the res/drawable folder for the app you are targeting). This will give you a list of strings where each string is an asset name. Then you can simply use the same code you are using to obtain their identifiers.
